An Indian spacecraft Wednesday entered into Mars orbit in its maiden attempt by executing the crucial operation precisely to create history.

The final operation began at 4.17 a.m. when the spacecraft's medium antenna was first activated for signals and it was rotated towards Mars at 6.57 a.m.

"The burn was terminated at 7.54 a.m. when the required braking velocity was achieved and the spacecraft was reoriented to point its antenna towards earth for resuming communication with ground stations," the scientist said.

The Orbiter's speed was also reduced by 2.14 metres per second from 22.2 km per second for its smooth transition into Mars orbit from Sun orbit.
